Commonwealth Games silver medallist Michaela Walsh has bowed out of the World Championships in Delhi at the last-16 stage.
The Belfast featherweight was edged out on a 4-1 verdict by Italy's defending champion Alessia Mesiano.
Walsh defeated Mesiano by unanimous decision at the European Championships earlier this year on her way to clinching the bronze medal.
Cavan flyweight Ceire Smith also suffered a narrow last-16 defeat.
Three of the judges scored the fight level at 28-28 with the two others scoring it 29-27 to Smith in her bout with Japan's Namiki Tukimi.
But under the rules, the judges who had called the fight level then had to make a further decision and they all sided with Tukimi.
What made the decision even more galling for Smith was that the Japanese fight received a public warning in the final round for punching Smith in the back of the head.
